[0001] The utility model belongs to the technical field of furniture manufacturing, in particular to a turning device for spraying furniture panels. Background Art

[0002] Some parts of wooden furniture, such as chair backs and tabletops, are usually cut into rectangular shapes for easy assembly. Before assembling wooden furniture, the wooden boards need to be painted. Painting not only prevents the wood from being damp and deformed due to contact with air, but also makes the color of the wood brighter and effectively prevents insect erosion, thereby extending the service life of the furniture.

[0003] However, when spraying paint on the outer surface of wooden furniture, the upper and lower surfaces of the board need to be sprayed at the same time according to the process requirements of spraying paint. Since the board is generally made of solid wood and has a large weight, it is very inconvenient to turn it over manually, and it is easy to cause damage to the surface of the board due to scratches and collisions, thereby affecting the quality of the finished wooden furniture.

[0004] Therefore, in order to solve the problem of difficulty in manually turning over the plate to spray paint on the back, we urgently need to design a device to replace manual labor to achieve rapid turning over and efficient painting of the plate. Utility Model Content

DETAILED DESCRIPTION

[0032] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] This embodiment describes a turning device for spraying furniture panels, including two transmission shafts 35 and two fixing mechanisms;

[0034] The two fixing mechanisms are symmetrically arranged and connected by two transmission shafts 35. Each of the fixing mechanisms includes a base 10, a driving assembly 40, a supporting wall 50, a clamping assembly 60, two supporting blocks 20 and two lifting assemblies 30.

[0035] Two symmetrically arranged support blocks 20 are provided at the upper end of the base 10, and placement grooves are provided on the opposite surfaces of the two support blocks 20 along the length direction. One end of the two transmission shafts 35 are respectively rotated to penetrate into the corresponding placement grooves, and a driving assembly 40 is provided between the two transmission shafts 35. A lifting assembly 30 is provided in each placement groove and is fixedly connected to the corresponding transmission shaft 35. A support wall 50 is fixed between the two lifting assemblies 30, and the clamping assembly 60 is slidably inserted into the support wall 50.

[0036] Each of the lifting assemblies 30 includes a threaded block 31, a lead screw 32, a turbine 33 and a worm 34;

[0037] The threaded block 31 is slidably embedded in the corresponding placement groove and fixedly connected to the support wall 50. The threaded block 31 is threadedly connected to the screw 32. One end of the screw 32 is rotatably connected to the base 10. A turbine 33 is provided on the screw 32. The turbine 33 is meshedly connected to the worm 34. The worm 34 is fixedly mounted on the corresponding transmission shaft 35.

[0038] The driving assembly 40 includes a chain 42 and two sprockets 41;

[0039] The two sprocket wheels 41 are respectively mounted and fixed on the corresponding transmission shafts 35 , and the two sprocket wheels 41 are connected through a chain 42 .

[0040] The support wall 50 is provided with a first guide groove 51 and a second guide groove 52 , respectively. One end of the first guide groove 51 and the second guide groove 52 is arc-shaped and the other end is horizontal.

[0041] The clamping assembly 60 includes a fixing frame 61, a square slot 63, a clamping plate 64, a bolt 65 and two cylindrical pins 62;

[0042] One side of the fixing frame 61 is provided with two parallel cylindrical pins 62, which are respectively slidably inserted into the corresponding first guide groove 51 and the second guide groove 52. The other side of the fixing frame 61 is provided with a square groove 63, in which a clamping plate 64 is slidably embedded. The upper end of the fixing frame 61 is evenly provided with a plurality of threaded holes along the length direction. The bolts 65 are threadedly connected with the corresponding threaded holes, and the clamping plate 64 is fixed by the bolts 65.

[0043] The flipping device for spraying furniture panels also includes a handle 43 , wherein one end of one of the transmission shafts 35 extends out of the placement slot and is fixedly connected to the handle 43 .

[0044] When using the utility model, first, the overall structure of the device allows the plate to be fixed in the clamping assembly 60. The clamping assembly 60 can be adjusted according to the size of the plate through the coordinated use of the bolts 65 and the clamping plate 64 to ensure that the plate is firmly fixed on the fixing frame 61. At this time, the clamping assembly 60 is in a horizontal state with the plate, which is convenient for spraying paint on the upper surface of the plate.

[0045] During the painting process, if the plate needs to be turned over to paint its lower surface, the operator can push the clamping assembly 60 to rotate it in the supporting wall 50. Since the clamping assembly 60 is connected to the first guide groove 51 and the second guide groove 52 on the supporting wall 50 respectively through two cylindrical pins 62, when the clamping assembly 60 is subjected to a thrust, the cylindrical pin 62 will move along the track of the guide groove. When the cylindrical pin 62 moves from the horizontal section of the guide groove to the arc section, the clamping assembly 60 and the plate will no longer be restricted by the horizontal section, but will begin to turn over due to the action of their own gravity.

[0046] During the flipping process, since the plate and the clamping assembly 60 have mass, they will rotate around the slot of the arc segment until they reach a vertical position, completing the flipping of the plate. In order to prevent the center of gravity of the plate and the clamping assembly 60 from being biased to an undesirable side during flipping, the arrangement direction of the two cylindrical pins 62 should be carefully designed to ensure that the plate can be smoothly flipped to the desired position.

[0047] In addition, the device is also designed with a lifting assembly 30 and a driving assembly 40 for adjusting the vertical position of the supporting wall 50 and the clamping assembly 60. By turning the handle 43, the transmission shaft 35 and the worm 34 can be driven to rotate, and then the threaded block 31 can be vertically lifted through the threaded transmission of the turbine 33 and the lead screw 32. Since the lifting assemblies 30 are provided in four groups and distributed at the four corners of the base 10, when the handle 43 is turned, the synchronous lifting of the four lifting assemblies 30 can be achieved through the synchronous rotation of the sprocket 41 and the chain 42, thereby ensuring that the supporting wall 50 and the clamping assembly 60 are lifted and lowered smoothly.

[0048] In summary, the turning device for spraying furniture panels realizes the rapid turning and position adjustment of panels through the coordinated work of the clamping assembly, the supporting wall, the lifting assembly and the driving assembly, which greatly improves the efficiency and convenience of painting. At the same time, the design of the device takes stability and safety into consideration, ensuring the stability of the panels during turning and painting and the quality of the finished products.

Therefore, the embodiments should be considered exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalents of the claims be included in the present invention.
